5101 Wisconsin

How does 5101 Wisconsin compare with other office buildings in Washington, DC?

The latest disclosures cover 899 office buildings in Washington, DC, out of 6,870 buildings citywide. 5101 Wisconsin's ENERGY STAR score of 80 compares with an average of 70 across the 774 that report a score; it scores higher than 63% of them and lower than 34%. Its site EUI of 39.8 kBtu/ft² is about 28% below the average of 55.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.5 kgCO₂e/ft² is about 30% below the group average of 5.0 kgCO₂e/ft².

At 61,855 sq ft, it is about 71% below the average floor area of 216,135 sq ft for those buildings. Its 1976 construction date is close to the group's average year built (1974). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has 5101 Wisconsin's energy performance changed over time?

BuildingCensus holds 12 Washington, DC disclosures for 5101 Wisconsin, covering report years 2013–2024. Its ENERGY STAR score went from 57 in 2013 to 80 in 2024 (+23 points); its best year on file was 2023, at 85. Site EUI moved from 70.2 kBtu/ft² (2013) to 39.8 kBtu/ft² (2024), a 43% decrease. Reported emissions went from 551 tCO₂e to 216 tCO₂e over the same span (down 61%).

What does an ENERGY STAR score of 80 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 80 means the building performs better than about 80% of its national peers. BuildingCensus bands the score into report-card grades; 80 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Washington, DC, 47% of scored buildings are at 75 or above.

Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 5101 Wisconsin's 39.8 kBtu/ft² across 61,855 sq ft works out to about 2.5 billion Btu (721 MWh-equivalent) in 2024. Its source EUI of 111.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 720,973 kWh of electricity, 0 therms of natural gas and 275 thousand gallons of water for the year.

Which law requires 5101 Wisconsin to report its energy use?

5101 Wisconsin reports under the Clean and Affordable Energy Act / BEPS, the legal basis of Washington, DC's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record dc:PM2256994:2024). DC's Building Energy Performance Standards (BEPS) require buildings below the performance standard to improve over compliance cycles (the first ends December 31, 2026; later cycles run five years), with penalties for buildings that fail to meet their pathway.
